Towards a dephasing diode: asymmetric and geometric dephasing
Robert S. Whitney, Alexander Shnirman, Yuval Gefen
We study the effect of a noisy environment on spin and charge transport in ballistic quantum wires with spin-orbit coupling (Rashba coupling). We find that the wire then acts as a…
Weak values of electron spin in a double quantum dot
Alessandro Romito, Yuval Gefen, Yaroslav M. Blanter
We propose a protocol for a controlled experiment to measure a weak value of the electron's spin in a solid state device. The weak value is obtained by a two step procedure -- weak…
Zero bias anomaly out of equilibrium
D. B. Gutman, Yuval Gefen, A. D. Mirlin
The non-equilibrium zero bias anomaly (ZBA) in the tunneling density of states of a diffusive metallic film is studied. An effective action describing virtual fluctuations out-of-e…
Suppression of Visibility in a Two-Electron Mach-Zehnder Interferometer
Ya. M. Blanter, Yuval Gefen
We investigate the suppression of the visibility of Aharonov-Bohm oscillations in a two-electron Mach-Zehnder interferometer that leaves the single-electron current unchanged. In t…
Decoherence of Rabi oscillations of electronic spin states in a double quantum dot
Alessandro Romito, Yuval Gefen
We study the role of charge fluctuations in the decoherence of Rabi oscillations between spin states |>, |> of two electrons in a double d…
Decoherence and interactions in an electronic Mach-Zehnder interferometer
J. T. Chalker, Yuval Gefen, M. Y. Veillette
We develop a theoretical description of a Mach-Zehnder interferometer built from integer quantum Hall edge states, with an emphasis on how electron-electron interactions produce de…
